Bax,

The problem occurs with the engine running or not.

We did add the heaver gauge extensions. The plane is setup per the manual and I believe the leads back to the elevator and rudder are probably 24" plus the length of the servo wires...so pretty long.

I'll check the promiximity wires to the Nimh 2400mah battery.

Regarding "RF chokes or ferrite beads", where can I get these?

Thanks again,
John
